Function Documentation

void errorHandler	(	void *	ctx,
		const char *	msg,
			...
	)

Error handler for libxml2.

Definition at line 43 of file CommonConvert.cpp.

static void FindInstances ( FCDSceneNode *  node, std::vector< FoundInstance > &  instances, const FMMatrix44 &  transform, bool  onlyMarked  )

static

Recursively finds all entities under the current node.

If onlyMarked is set, only matches entities where the user-defined property was set to "export" in the modelling program.

Parameters

node	root of subtree to search
instances	output - appends matching entities
transform	transform matrix of current subtree
onlyMarked	only match entities with "export" property

Definition at line 232 of file CommonConvert.cpp.

bool FindSingleInstance	(	FCDSceneNode *	node,
		FCDEntityInstance *&	instance,
		FMMatrix44 &	transform
	)

Tries to find a single suitable entity instance in the scene.

Fails if there are none, or if there are too many and it's not clear which one should be converted.

Parameters

node	root scene node to search under
instance	output - the found entity instance (if any)
transform	- the world-space transform of the found entity

Returns

true if one was found

Definition at line 265 of file CommonConvert.cpp.

const Skeleton& FindSkeleton

(

const FCDControllerInstance &

controllerInstance

)

Finds the skeleton definition which best matches the given controller.

Exceptions

ColladaException

if none is found.

Definition at line 381 of file CommonConvert.cpp.

void FixSkeletonRoots

(

FCDControllerInstance &

controllerInstance

)

Fixes some occasional problems with the skeleton root definitions in a controller.

(In particular, it's needed for models exported from XSI.) Should be called before extracting any joint information from the controller.

Definition at line 363 of file CommonConvert.cpp.

FMMatrix44 FMMatrix44_Identity

(

identity

static bool ReverseSortWeight ( const FCDJointWeightPair &  a, const FCDJointWeightPair &  b  )

static

Definition at line 298 of file CommonConvert.cpp.

void SkinReduceInfluences	(	FCDSkinController *	skin,
		size_t	maxInfluenceCount,
		float	minimumWeight
	)

Like FCDSkinController::ReduceInfluences but works correctly.

Additionally, multiple influences for the same joint-vertex pair are collapsed into a single influence.

Definition at line 303 of file CommonConvert.cpp.

void TransformBones	(	std::vector< BoneTransform > &	bones,
		const FMMatrix44 &	scaleTransform,
		bool	yUp
	)

Performs the standard transformations on bones, applying a scale matrix and moving them into the game's coordinate space.
